Abstract
Process for obtaining foamable styiric polymers, using as an expansion agent easily volatizing hydrocarbons, aliphatic or aliphatic cycles, liquids at room temperature, characterized in that the fine granular styolic polymers are treated in closed containers with mixtures of predominant amounts of water with small amounts of aliphatic or cycloaliphatic hydrocarbons with easy volatilization at higher temperatures, but below the softening point of the styolic polymers.
